API Quickstart

This page shows you how to get started with the Google Analytics Data API v1 in your favorite programming language using the client Libraries.

Step 1. Enable the API

Click this button to create a new Cloud Platform project, automatically enable the Google Analytics Data API v1 and create the service account needed for this tutorial:

Enable the Google Analytics Data API v1

In resulting dialog click DOWNLOAD CLIENT CONFIGURATION and save the file credentials.json to your working directory.

Step 2. Add service account to the Google Analytics 4 property

Using a text editor, open the credentials.json file downloaded in the previous step and search for client_email field to obtain the service account email address that looks similar to:

quickstart@PROJECT-ID.iam.gserviceaccount.com

Use this email address to add a user to the Google Analytics 4 property you want to access via the Google Analytics Data API v1. For this tutorial only Read & Analyze permissions are needed.

Step 3. Configure authentication

This application demonstrates the usage of the Google Analytics Data API v1 using service account credentials.

Read more for instructions on creating and setting service account credentials for your application.

An easy way to provide service account credentials is by setting the GOOGLE_APPLICATION_CREDENTIALS environment variable, the API client will use the value of this variable to find the service account key JSON file.

To set the application credentials in this example, run the following command and use the path to the service account JSON file downloaded at Step 1:

export GOOGLE_APPLICATION_CREDENTIALS="[PATH]"

For example:

export GOOGLE_APPLICATION_CREDENTIALS="/home/user/Downloads/credentials.json"

Step 4. Install the client library

Make an API call

Now you can use the Google Analytics Data API to query a Google Analytics 4 property. Run the following code to perform your first call to the API:

Java

import com.google.analytics.data.v1beta.BetaAnalyticsDataClient;
import com.google.analytics.data.v1beta.DateRange;
import com.google.analytics.data.v1beta.Dimension;
import com.google.analytics.data.v1beta.Metric;
import com.google.analytics.data.v1beta.Row;
import com.google.analytics.data.v1beta.RunReportRequest;
import com.google.analytics.data.v1beta.RunReportResponse;

public class QuickstartSample {

  public static void main(String... args) throws Exception {
    /**
     * TODO(developer): Replace this variable with your Google Analytics 4 property ID before
     * running the sample.
     */
    String propertyId = "YOUR-GA4-PROPERTY-ID";
    sampleRunReport(propertyId);
  }

  // This is an example snippet that calls the Google Analytics Data API and runs a simple report
  // on the provided GA4 property id.
  static void sampleRunReport(String propertyId) throws Exception {
    /**
     * TODO(developer): Uncomment this variable and replace with your Google Analytics 4 property ID
     * before running the sample.
     */
    // propertyId = "YOUR-GA4-PROPERTY-ID";

    // Using a default constructor instructs the client to use the credentials
    // specified in GOOGLE_APPLICATION_CREDENTIALS environment variable.
    try (BetaAnalyticsDataClient analyticsData = BetaAnalyticsDataClient.create()) {

      RunReportRequest request =
          RunReportRequest.newBuilder()
              .setProperty("properties/" + propertyId)
              .addDimensions(Dimension.newBuilder().setName("city"))
              .addMetrics(Metric.newBuilder().setName("activeUsers"))
              .addDateRanges(DateRange.newBuilder().setStartDate("2020-03-31").setEndDate("today"))
              .build();

      // Make the request.
      RunReportResponse response = analyticsData.runReport(request);

      System.out.println("Report result:");
      // Iterate through every row of the API response.
      for (Row row : response.getRowsList()) {
        System.out.printf(
            "%s, %s%n", row.getDimensionValues(0).getValue(), row.getMetricValues(0).getValue());
      }
    }
  }
}
